From 6bdab60d5cbd7996e371305433e943a82cde0d4c Mon Sep 17 00:00:00 2001 From: Naman Jain Date: Fri, 27 Jan 2023 09:42:00 +0530 Subject: [PATCH] soc: qcom: socinfo: Add support for new field in revision 17 Add support for new field coming with socinfo structure under v17 to get hardware platform's oem variant id. This is to enable OEMs to have minor changes in the board, but to use the same platform subtype as the one supported by Qualcomm. The new field is to be used in platform overlay file. Default value is 0, reserved for Qualcomm platforms. Also, add debugfs support to read this field for a device.
